  By the way, regarding the air conditioning system mounted on the autonomous driving vehicle, the inventor has conducted extensive research on improving passenger comfort and found a new problem. That is, in the automatic driving vehicle, the backrest of the front seat can be largely tilted and the occupant can sit on the backrest in the automatic driving mode. In this case, when the conditioned air is blown out from the outlet of the instrument panel closest to the front seat where the occupant sits down, it is difficult to deliver the conditioned air to the upper body of the seated occupant drowned in the back seat of the front seat. May be. Therefore, in the technique described in Patent Document 1 described above, when an occupant is seated in a state in which the backrest of the front seat is greatly lowered, an optimum outlet is selected only by detecting the seat on which the occupant is seated. There is a problem that it can not be said that it will be

  An object of the present invention is to provide an air conditioning system capable of improving the comfort of a passenger seated in a state where the backrest of the front seat is greatly lowered.

In order to achieve the above object, the invention according to claim 1
An air conditioning system mounted on a vehicle (2) having a front seat (3) capable of adjusting the angle of the backrest (31),

A first outlet (100) provided in front of the vehicle with respect to the front seat and blowing out the conditioned air generated by the air conditioner;
A second blow is provided at a position rearward of the vehicle from the first outlet and in a position where air conditioning can be blown out to the front seat space (FS) and the rear seat space (RS), and blowing out the air conditioning wind generated by the air conditioner. Exit (200),
A backrest angle detector (32) for detecting the backrest angle of the front seat;
When the air conditioning system is operating and it is detected by the backrest angle detection unit that the backrest of the front seat is tilted more than a predetermined angle, the conditioned air is blown out from the second air outlet into the front seat space And a control device (40) for controlling as described above.

  According to this, when the air conditioner is operating and the front seat occupant tilts the backrest of the front seat beyond a predetermined angle, the conditioned air is blown out from the second air outlet into the front seat space. The conditioned air is delivered to the upper body of the occupant seated in the front seat. Therefore, this air conditioning system can improve the comfort of the passenger seated in a state where the backrest of the front seat is greatly lowered.

  In addition to the conditioned air blown out from the first outlet, the conditioned passenger blown out from the second outlet is used for the occupant sitting in a state where the back seat of the front seat is largely turned down. Air conditioning can be performed for each part of the human body.

  Further, when the backrest of the front seat is greatly lowered, the distance between the upper body of the occupant seated in the front seat and the second air outlet becomes closer. Therefore, by performing air conditioning on the occupant using the conditioned air blown out from the second air outlet located at a position close to the upper body of the occupant, it becomes possible to perform air conditioning on the occupant with a small amount of air. Therefore, this air conditioning system can reduce the energy consumed by the air conditioner and improve the fuel efficiency of the vehicle.

  The air conditioning system 1 of the first embodiment includes a first air conditioner 10, a second air conditioner 20, and a second wind direction adjusting plate 210 according to the angle of the backrest 31 of the front seat 3 and the presence or absence of the passenger 7 in the rear seat 4. Is a configuration that is driven and controlled by the control device 40. The angle of backrest 31 of front seat 3 is detected by backrest angle detection unit 32. The backrest angle detection unit 32 can employ a sensor that mechanically detects the angle of the backrest 31 of the front seat 3 in a contact or non-contact manner. Alternatively, when a switch operated by the occupant 6 is provided to adjust the angle of the backrest 31 of the front seat 3, the backrest angle detection unit 32 may be configured to acquire a signal of the switch. It is. Information regarding the angle of the backrest 31 of the front seat 3 detected by the backrest angle detection unit 32 is transmitted to the control device 40.

  The presence or absence of the occupant 7 in the rear seat 4, that is, whether or not the occupant 7 is seated in the rear seat 4 is detected by the rear seat occupant detection unit 33. The rear seat occupant detection unit 33 can adopt a seating sensor provided in the seat portion of the rear seat 4 or an infrared sensor (not shown). Information regarding the presence or absence of the occupant 7 in the rear seat 4 detected by the rear seat occupant detection unit 33 is also transmitted to the control device 40.

  The control device 40 is configured by a computer having a processor, a memory, and the like, and peripheral circuits thereof. The memory of the control device 40 is configured of a non-transitional tangible storage medium. The control device 40 may be configured integrally with the air conditioning control device for driving the first air conditioner 10 and the second air conditioner 20 described above, or may be configured as separate members.

  Control processing executed by the control device 40 will be described with reference to the flowchart of FIG. 5 and the like. This control process is repeatedly performed after the ignition switch of the vehicle 2 is turned on.

  First, in step S10, the control device 40 determines whether or not the front seat space FS is air-conditioned by the first air conditioner 10. The controller 40 may determine whether the first air conditioner 10 is driving. Moreover, you may determine by the control apparatus 40 acquiring the output signal of the air-conditioning operation switch which is provided in the instrument panel 8 in order that the passenger | crew 6 may operate.

  When the front seat space FS is not air-conditioned by the first air conditioner 10, the control device 40 once ends the process. Then, the control device 40 repeatedly executes the process from step S10 again. On the other hand, when the front seat space FS is air-conditioned by the first air conditioner 10, the control device 40 moves the process to step S20.

  Next, in step S <b> 20, the control device 40 determines whether the backrest 31 of the front seat 3 is tilted over a predetermined angle based on the signal transmitted from the backrest angle detection unit 32. For example, when the conditioned air is blown out from the second air outlet 200 toward the front seat space FS, the predetermined angle is on the upper body of the occupant 6 who sits on the backrest 31 of the front seat 3 and sits down. It can be defined as a standard whether or not it is supplied. When the backrest 31 of the front seat 3 is not tilted beyond a predetermined angle, the control device 40 once ends the process. Then, the control device 40 repeatedly executes the process from step S10 again. On the other hand, when the backrest 31 of the front seat 3 is tilted over a predetermined angle, the control device 40 proceeds to step S30.

  Subsequently, in step S <b> 30, the control device 40 determines whether or not the occupant 7 is seated in the rear seat 4 based on the signal transmitted from the rear seat occupant detection unit 33. If the occupant 7 is not seated in the rear seat 4, the control device 40 proceeds to step S40.

  In step S40, the control device 40 drives the second air conditioner 20, and controls the second air direction adjusting plate 210 so that the conditioned air is blown from the second air outlet 200 to the front seat space FS. As a result, as shown by arrow AF2 in FIG. 2, the conditioned air blown out from the second air outlet 200 into the front seat space FS is supplied to the upper body of the occupant 6 seated on the backrest 31 of the front seat 3. Is done. That is, the conditioned air blown out from the second outlet 200 into the front seat space FS is delivered to a portion where it is difficult to send the wind only with the conditioned air blown out from the first outlet 100. As a result, the occupant 6 seated in the front seat 3 is the conditioned air blown out from the first outlet 100 of the first air conditioner 10 and the conditioned air blown out from the second outlet 200 of the second air conditioner 20. Both will comfortably air-condition the whole body.

  If the occupant 7 is seated on the rear seat 4 in step S30 described above, the control device 40 once ends the process. At that time, as shown by an arrow AF3 in FIG. 6, if the conditioned air is blown from the second air outlet 200 of the second air conditioner 20 to the rear seat space RS, the control device 40 maintains that state. Therefore, as indicated by an arrow AF1 in FIG. 6, conditioned air is blown from the first air outlet 100 of the first air conditioner 10 to the front seat space FS, and as indicated by an arrow AF3 in FIG. The conditioned air is blown out from the second blowout port 200 of the rear seat space RS. As a result, the comfort of the occupant 6 seated in the front seat 3 and the comfort of the occupant 7 seated in the rear seat 4 are maintained. After temporarily ending the process, the control device 40 repeatedly executes the process described above from step S10.

  Next, in step S50, the control device 40 determines whether or not the eco mode is selected by the occupant 6. The eco mode is an operation mode for improving the fuel efficiency of the vehicle 2, and may be called an eco drive mode or an economy mode. The eco mode is executed when the occupant 6 turns on an eco mode switch installed in the vehicle interior. When the eco mode is not selected by the occupant 6, the control device 40 once ends the process. Then, the control device 40 repeatedly executes the process from step S10 again. On the other hand, when the eco mode is selected by the occupant 6, the control device 40 proceeds to step S60.

  Subsequently, in step S60, the control device 40 determines whether the air conditioning request is set to max hot or max cool (that is, whether the air conditioning request is set to the maximum output of cooling or heating). When the air conditioning request is not set to max hot or max cool, the control device 40 proceeds to step S70.

  In step S70, the control device 40 stops the driving of the first air conditioner 10. In that case, since the air conditioning for the occupant 6 seated in the front seat 3 is mainly performed by the second air conditioner 20, the influence on the comfort of the occupant 6 is small even if the driving of the first air conditioner 10 is stopped. It becomes. Therefore, the air conditioning system 1 can reduce the energy consumed for air conditioning in the vehicle interior by stopping the driving of the first air conditioner 10 and improve the fuel efficiency of the vehicle 2. In step S70, the control device 40 may reduce the air conditioning capability of the first air conditioner 10 instead of stopping the driving of the first air conditioner 10. Also by doing this, the air conditioning system 1 can reduce the energy consumed by the first air conditioner 10 and improve the fuel consumption of the vehicle 2.

  When the air conditioning request is set to max hot or max cool in step S60 described above, the control device 40 once ends the process and repeats the process from step S10 again. In that case, the control device 40 does not perform control for stopping driving of the first air conditioner 10 or control for reducing the air conditioning capability of the first air conditioner 10. Thereby, when the air conditioning request is set to the maximum output of cooling or heating, the comfort of the occupant 6 is achieved by driving both the first air conditioner 10 and the second air conditioner 20 to air-condition the occupant 6. Can increase the sex.

The air conditioning system 1 of 1st Embodiment demonstrated above has the following effect.
(1) In the first embodiment, when the first air conditioner 10 is in operation, and the backrest 31 of the front seat 3 is turned over at a predetermined angle or more, the control device 40 is located in front of the second outlet 200 Control is performed so that conditioned air is blown out to the seat space FS. As a result, the conditioned air is delivered from the second air outlet 200 to the upper body of the occupant 6 seated in the front seat 3 in a state in which the backrest 31 is turned over a predetermined angle or more. Therefore, when the occupant 6 is seated with the backrest 31 of the front seat 3 largely turned down, the air conditioning system 1 can enhance the comfort of the occupant 6.

  In addition to the conditioned air blown out from the first outlet 100, the conditioned air blown out from the second outlet 200 is used for the occupant 6 seated in the front seat 3 in a state where the backrest 31 is largely turned down. Thus, air conditioning can be performed for each part of the human body of the occupant 6.

  Furthermore, when the backrest 31 of the front seat 3 is largely turned down, the distance between the upper body of the occupant 6 seated in the front seat 3 and the second air outlet 200 becomes close. Therefore, by performing air conditioning on the occupant 6 using the conditioned air blown out from the second outlet 200 located at a position close to the upper body of the occupant 6 seated in the front seat 3, the air conditioning for the occupant 6 can be performed with a small air flow. Can be done. Therefore, the air conditioning system 1 can reduce the energy consumed by the first air conditioner 10 and the second air conditioner 20, and improve the fuel efficiency of the vehicle 2.

  (2) In the first embodiment, when the first air conditioner 10 is operating and the backrest 31 of the front seat 3 is tilted over a predetermined angle, the control device 40 moves forward from the second air outlet 200. The second air direction adjusting plate 210 is driven and controlled so that the conditioned air is blown out to the seat space FS. According to this, by the drive control of the second air direction adjusting plate 210, the direction of the conditioned air blown out from the second air outlet 200 is automatically adjusted. Therefore, in the air conditioning system 1, when the backrest 31 of the front seat 3 is turned to a predetermined angle or more, the second wind direction adjustment plate 210 is driven to control any of the front seat space FS from the second outlet 200. It is possible to blow out the conditioned air toward the place.
